Antenna radiation pattern reconfiguration using multi-stability

Main content start

We investigate mechanically reconfigurable antennas as a means of creating flexible emergency communications infrastructure for disaster relief and low-infrastructure areas. Mechanical reconfiguration of conductors allows to create low-cost, energy-efficient, and lightweight solutions that can simultaneously adapt their performance to a changing environment. As such, we are studying reconfigurable helical lattice structures as a means of adapting performance in helical antennas. Our research is focused on several aspects:

  • Investigation of the link between helix shape and antenna radiation pattern (where it sends its signal) 
  • Integration of multi-stability into helical structures to enable low-energy reconfiguration
  • Lightweight smart material actuation
  • Manufacturing of novel composite materials that enable the desired multi-stability and are low-cost
